A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The detector which operates based on detection of heat or temperature is known as heat detector. One bimetal strip has a higher thermal inertia either because it is lagged, as shown in the figure, or because it is thermally shielded from the space being. This tends to lead to fewer false alarms. A hand held laser tool can also be used in conjunction with the vision range of detectors for triggering the vision detector. A rate of rise detector looks at temperature change over time. Heating causes an increase in air pressure inside the detector. Measuring the change in temperature provides a faster alarm response than measuring the temperature level in a space. 1 tup‐40 heat detector design 5 principle of operation the tup‐40 heat detector reacts to rise of temperature which occurs in the initial ik‐e291‐001gb 5 table 1 rate of air temperature rise from typical operation temperature k/min 1 3 5 10 20 30 a1r class minimum maximum actuation time.
